Question
What are metal concentrations in lake sediments? The focus is on Finland.
Answer
1) Calculate the metal concentration based on the mean value of the surrounding lakes (spherical area specified by radius)
2) Calculate the concentration based on the concentration of a big lake
<rcode graphics="1" include="page:OpasnetBaseUtils|name:generic"
variables="
name:name of the big lake|description:Name of the big lake|default:1|
name:concentration in big lake|description:Concentration in big lake|default:1|
name:coefficient for pH|description:Coefficient for pH|default:1|
name:coefficient for land use|description:Coefficient for land use|default:1|
library(OpasnetBaseUtils) library(xtable) library(ggplot2) library(reshape)
concentration <- "concentration in big lake" * "coefficient for pH" * coefficient for land use </rcode>
Rationale
Based on data from GTK, Finland.
